- FLOOR-PLANING TQOL.

Specification of Letters Patent.

Patented Sept. 15,1908.

. Application filed July 28, i906. Serial No. 328,257.

provide a machine of this type adapted to be moved over the fioor and plane the surface thereof.

p The invention may be said briefly to consist of a carriage adapted to skid alon the surface of the floor and having a rotary knife mounted thereon and means for varying the extentto which the knife cuts into the surface of the floor such rotary knife consisting of a rotary device having a series of blades mounted thereon while such blades act upon the surface of the floor through an opening in the frame of the machine.

For .full comprehension, however, of my invention reference must be had to accompanying drawin s forming a art of .this specification in w ich similar re erencecharacters indicate the same parts and wherein Figure 1, is a side elevation of a floor planing machine constructed according to my. invention, Fig. 2. is a plan view thereof, Fig. 3. is a frontelcva'tion, Fig. 4. is a transverse vertical sectional view ofthe base plate alone taken on line was 2.

My im roved planin cited as at e to the rear of the plate and the latter is threaded. into a socket 9 preferablyformed in one with such plate and pi 'efe'arablyv located at the front thereof. p In the preferred embodiment of my invention bearings h h are located near t 0 front of the plate one at each side thereof and an adjustable plate 7', is fulcrumed at its forward end, upon a spindle 9' supported in such bearings. A pillow block k s bolted to the top of this "carrying'plate and has a bearing 1 at its upper end in which is. sup orted a driving shaft n upon one end of whlc is mounted the rotary part indicated by dotted lines at p while a driving pinion m is mounted rigidly upon the o posite end thereof. "A cylinderr carried by t is pillow block incloses the rotary part 1). and has a motive fluid lntake'duct s to which is connected aflexible tubular -con tool consists' of a plate I) a ,apted to be sli along the fioor by a:

air of handles 0 d the former of which is I E p when it is desired to move the machine withductor't. leading from any available source (not shown). The pillow block also affords a bearing for a driven shaft u and a counter shaft '2) intermediate such driving and driven shafts between which an operative connection is established by a train of gears 2 3 and 4-. the two first of which (2 and 3) are mounted upon the counter shaft '0 and the first mentioned intermeshing with the driving pinion m while the last mentioned gear (3) intermeshes with the gear 4 which is mounted upon the driven shaft u.

rotary cutter. This rotary cutter preferably consists of a square carrying member, 10,

-.top of the base plate, the function thereof bo ing to limit the extent to which the cutting ed es will project below the base plate, while a ocle-nut 16 upon the adjusting. screw sets the latter against accidental displacement. A lever fulcruined adjacent to thetop of the rear handle is connected b a rod, 17, to the realism]. of the carrying p ate, as at'18, the

lfted out of engagement with the floor out the cutter being in operation. If desired the device can be utilized for dopurpose thereof being to enable the cutter to v This driven shaft 1 has its free end squared as at 5 to receive the ing bench work the rotary cutter being removed and a circular saw as indicated at 60 substituted therefor while the base plate will be clamped at one end of the bench.

What I claim is as follows 1. A floor planing tool consisting of a base plate adapted tobe. slid upon the floor and aving, an opening therein, a plate located I above such base plate and pivoted at one end thereto, a rotary cutter supported upon the adjustable plate in position to have the cutting portion thereof project throughtheo ening in such base plate, a pair of handleare fromthe base Qplate,

ro'ectin u wardl p J g p fiilcrumed to pne of the a bell crank lever handle bars nearthc handle portionzthereof,

A floor plai'iing tool consisting of a; base ing the normal position of the pivoted plate f relatively to the base plate and means whereby the rotary cutter is driven.

3. A floor planing tool comprising a base plate having on opening; :1 plane pivoted at one end to the base plate and carrying a transverse shalt; n rotor \"'cutter nlounted see,

upon one end oi: such shaft and a gear upon the opposite end thereot the cutter being in uxteposition with the opening in the base plate and adapted to be projected theretln'ough; a counter shaft carried by such-pivoted platefa gear mounted. upon one end of the counter shaft and 'interlneshing with the first mentioned gear, and a motor upon the opposite end of such counter shaft n pair of handle bars carried by opposite ends of the base plate; a bell crank lever mounted near thetop of one of such. handle bars and a link connecting such bell-crank-levcr to the free end of the pivoted plate; and a screw carried by the said. pivoted plate and bearing upon the base plate/fl er the purpose set forth.

In testimony whereof, l. have signed my l name to this specification, in the 1'nesence oi two subscribing witnesses.
